Glycolysis is the first stage of cellular respiration, where glucose is broken down into two molecules of pyruvate.

The primary function of glycolysis is to generate pyruvate, which is then used in the Krebs Cycle.

During glycolysis, 2 molecules of ATP are produced.

The Krebs Cycle, also known as the Citric Acid Cycle, is the second stage of cellular respiration.

The primary function of the Krebs Cycle is to produce NADH and FADH2, which are high-energy electron carriers.

During the Krebs Cycle, 2 molecules of ATP are produced.

The Electron Transport Chain is the third stage of cellular respiration.

The primary function of the Electron Transport Chain is to produce ATP through a process called oxidative phosphorylation.

During the Electron Transport Chain, 32 molecules of ATP are produced.

Oxidative Phosphorylation is the final stage of cellular respiration.

The primary function of oxidative phosphorylation is to produce ATP through the transfer of electrons from NADH and FADH2 to oxygen.

During oxidative phosphorylation, 32 molecules of ATP are produced.

During cellular respiration, a total of 38 molecules of ATP are produced.

Oxygen is the final electron acceptor in the Electron Transport Chain.

Acetyl CoA is the molecule that carries high-energy electrons from glycolysis to the Krebs Cycle.
